Fly.io is expanding its server locations to Johannesburg, South Africa. Users can now launch full-stack apps in this region with ease. The text highlights the city's sports culture and cuisine, emphasizing that deploying an app in Johannesburg could benefit users who support local teams like the Springboks and Banyana Banyana.

LiteFS is a distributed file system that replicates SQLite databases across multiple servers. It now supports all journaling modes, including the write-ahead log (WAL) mode, which improves concurrency and write performance. LiteFS keeps distributed copies of databases in sync by tracking changes as "change sets" and communicating them between nodes. The new litefs import command simplifies converting an existing application to use LiteFS. Additionally, the reworked checksumming method ensures database consistency across all nodes. Improved debugging with the trace log helps identify issues in LiteFS. Upcoming work includes supporting write forwarding and adding LZ4 compression for better performance.
